How have jury instructions been interpreted in criminal cases?

In any event, jury instructions are not considered in isolation, and their adequacy is determined by consideration of the entire charge to the jury. (People v. Holt (1997) 15 Cal.4th 619, 677.) The jury instructions as given covered the nature of the required agreement between the codefendants, or other unknown individuals, to commit the crime of giving a controlled substance to a person in custody. The jury was told to decide each charge separately, and it filled out five separate verdict forms on the conspiracy charges. The instructions adequately presented the issue of how many conspiracies were represented in the evidence, without any need for an additional sua sponte instruction.
